7 Application filed July 16, 1924, Seria1.No. 726,400. Renewed May 1 6, 1927. t

This invention relates to liquid dispensing containers and what I term a squirt gun, particularly designed to project a liquid lubricant in a fine spray to apart of the ma chine or apparatus. 1

One of the objects of my invention is to provide a novel and improved dispensing means for containers and the like, particularly adapted for liquid .graphite or its equivalent lubricant, including a spray tube whereby the said lubricant may be projected to penetrate the particular portion of the machine or apparatus where desired.

Another object of my invention is to provide a dispensing device of the class described which is extremely simple in construction, highly cflicient in operation and use, practical, durable, capable of a multiplicity of uses in the various arts and cheap to manufacture wherebyits' commercial possibilities are greatly enhanced.

In the drawings,

Figure 1 is a longitudinal, sectional view v of the container and its dispensing means. Figure 2 is a detached view, partly in sec-v tion of the closure or cap and its inlet and outlet tubes.

Figure 3 is a plan of the closure. Referring now to the drawings wherein like reference characters designate corresponding parts throughout the several views,

5 designates a conventional type of metal container or can having a raised top 6 and a threaded opening for an internally threaded cap 7, such as shown by Figure 2 of the drawings.

My container and its dispensing means are particularly designed for dispensing a, lubricant, such as liquid graphite, or its equivalent, and toward that end, the cap is provided with a bent tube 8, soldered or otherwise connected to the cap, above re ferred to. A rubber bulb 9, having an ex- .tension 10, fits over the outer end of the tube 8, said bulb being provided with the well-knowntype of valve housing 11 and ball valve. 12, so as to force air into the container. The cap 7 is also provided with an outlet or spray tube 13, which extends through the cap, into the container, so that the lower end 14 lies adjacent the bottom. The upper end of the said tube extends at an obtuse angle from the top of the container and is provided with a bevelled edge and fine opening 15 whereby a spray or very fine stream of the lubricant may be pro ected when the bulb 9 is compressed. The said cap is provided with an aperture or opening 16 therethrough, which controls the'operation of the dispensing means, when the said opening is closed by placing the tip of the finger thereover when the bulb is compressed thus causing the air under pressureto force the liquid or lubricant up through the tube 13. Of course, when the opening is not closed, if the bulb 9 is compressed, the air will enter the container and pass out through the said opening. It will be observed that the outlet tube 13, within the container extends at an angle with respect to a line drawn through the longitudinal axis of said container, so that the very last drop oflubricant may be forced out of the container before it is to be refilled. The cap is providedwith a cork washer 1b which assists in making an air tight closure for the said container when the openinglB is closed as above set forth.

In actual use, the operator holds thecontainer with one hand, closing the opening with the tip of the index orforefinger, and compresses the bulb 9 so that the air forces the liquid out through the tube 13. The restricted outer end of the outlet tube, permits it to be inserted in very small openings or crevices, whereby the lubricant may penetrate the particular part of the machine or apparatus- Of course,'the closure inletand outlet tubes are so connected to the container that thelatter may be refilled from time to time so that the purchaser of the lubricant may utilize'the same container indefinitely.

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. the rightand privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended claim.

Having thus described my invention what I claim as new and desire to secure by United States Letters Patent is I therefore reserve I fit) The combination with a container having I of said air supply pipe, and a rigid fluid delivery pipe extending through another of said openings and fixed to the closure, said fluid delivery pipe having a shorter end portion extending upwardly and laterally from the closure and terminating in a nozzle hav ing a restricted discharge orifice and a longer end portion extending into the container to a point adjacent the bottom and one side of the latter, whereby fluid may be forced from 10 the container through the discharge orifice in an upwardly and laterally vdirected fine spray when the bulb is compressed and the remaining opening of the closure is closed by the finger.

' In testimony whereof I afiix my signature.
